This updated guide explains core technical-writing principles: prioritize plain language and active voice, use consistent punctuation and article rules (a/an by sound), prefer numerals for technical precision, and adopt documentation-as-code workflows. Clear technical writing improves product adoption, reproducibility, and career prospects in roles like documentation engineer and developer advocate.

Why technical writing matters

Technical writing shapes how people use products, reproduce experiments, and understand systems. Clear documentation reduces support requests, improves adoption, and helps teams move faster. In research, reproducible methods and well-documented results determine whether work influences the field.

Core principles

Keep language plain and sentences short. Use active voice and organize content with headings, lists, and examples. Readers often skim, so surface the most important actions and warnings near the top.

  • Prioritize clarity over flourish.
  • Be consistent: follow a style guide (team, company, or public such as Microsoft, Google, or Chicago) for decisions on punctuation, capitalization, and formatting.

Punctuation and grammar

Punctuation changes meaning. Commas, parentheses, and dashes can create or remove ambiguity. Favor simple sentence structures. Use the serial (Oxford) comma when your team's style guide requires it; otherwise pick one approach and apply it consistently.

  • Capitalize the first word of every sentence.
  • End sentences with a period, question mark, or - rarely - an exclamation point.

Articles: a vs. an

Use "a" before consonant sounds (a user, a URL) and "an" before vowel sounds (an hour, an API). The rule depends on pronunciation, not spelling: "an HTML file" if you say "aitch-tee-em-el"; "a HTML file" if you would pronounce the H silently (rare).

Numbers and numerals

Modern technical writing favors numerals for precision and scanability, especially for measurements, code, identifiers, dates, and percentages. Spell out numbers that begin sentences or when readability benefits from words. Be consistent with your chosen style guide.

Practical formats and tools

Many teams use Markdown, version control (Git), and "documentation-as-code" workflows so docs can be reviewed, tested, and versioned with code. Use code blocks for examples, and include minimal working examples when you explain how something behaves.

Careers and impact

Technical writing roles now include documentation writers, content designers, developer advocates, and documentation engineers. Work can be freelance, in-house, or remote. Strong technical writing skills increase your influence: they make products easier to use, reduce customer friction, and help research be reproducible and reusable.

Quick checklist before publishing

  • Is the main action clear in the first 30 seconds?
  • Can a reader reproduce the steps or understand the concept without external help?
  • Are code examples minimal and tested?
  • Is formatting consistent with the team style guide?
Work on technical writing like any technical skill: get feedback, edit iteratively, and measure impact (fewer support tickets, higher task success, better reproducibility).

FAQs about Technical Writing Style

Should I always spell out numbers under ten?
Not necessarily. In technical contexts, numerals improve precision and scanability for measurements, code, dates, and percentages. Follow your team or chosen style guide and be consistent.
When do I use "a" versus "an"?
"A" precedes words that start with a consonant sound (a user, a URL). "An" precedes vowel sounds (an hour, an API when pronounced with a leading vowel sound). The rule follows pronunciation, not spelling.
What tools do technical writers commonly use today?
Many teams use Markdown with version control (Git) and documentation-as-code workflows to enable reviews, testing, and versioning alongside code. Use code blocks for examples and minimal reproducible samples.
How can technical writing affect product success?
Clear documentation reduces user friction, lowers support volume, increases adoption, and helps teams iterate faster. In research, it enables reproducibility and broader impact.
